Metal tube rotameter is a kind of flowmeter which is suitable for measuring flow of liquid and gas through floater movement inside metal tube.Data of flow can be read from dial scale thanks to magnetic coupling to act on signal transmitter.Output of electrical signal is 4-20mA.The rotameter can be used in any harsh working environment due to its shatter-proof, pressureproof, temperature-resistant and corrosion-resistant characteristics.

1. Features of the product 1. Double lines LCD, showing both instantaneous and accumulated flow.2. More stable signal output: construction of single axis and non-touching magnetic coupling.3. Fully metal-made body, suitable for high temperature, high pressure and corrosive media.4. Can be used even in flammable, explosive and harsh working environments. 5. Power supply: two-wire system, battery and AC for selection6. With functions of data recovery, backup and power failure protection7. New design for less pressure loss.
